FIG. 2 is an external view of the gas flow controller of the medical gas supply facility according to the present embodiment. FIG. 3 is an external view of a state in which the cover of the gas flow rate controller of the medical gas supply facility according to the present embodiment is removed.

  Hereinafter, an embodiment of the present invention will be described.

  FIG. 1 shows a configuration of a gas flow rate regulator according to the present embodiment and a medical gas supply facility 1 to which the gas flow regulator is attached. The medical gas supply facility 1 includes a gas supply source (not shown), an oxygen supply box 3, a gas flow rate regulator 10, and a humidifier 6. In addition, although oxygen gas is shown as an example of medical gas, not only this but gas, such as air, may be sufficient.

  A gas supply source (not shown) is provided outside the hospital room and supplies oxygen gas to an oxygen supply box 3 described later.

  The oxygen supply box 3 is attached to a wall surface 1 such as a hospital room, and oxygen is supplied from an oxygen supply source via a gas pipe 4. The oxygen supply box 3 is provided with a gas pipe 4 at the top and a gas outlet 5 at the front. An inlet plug 13 (see FIGS. 2 and 3) of the gas flow rate regulator 10 is inserted into the gas outlet 5, and the gas flow rate regulator 10 is attached to the oxygen supply box 3.

  In FIG. 2, the external appearance of the gas flow regulator 10 is shown. (1) of FIG. 2 is a front view, and (2) is a right side view. In FIG. 3, the external appearance of the state which removed the cover 40 of the gas flow regulator 10 is shown. FIG. 3 (1) is a perspective view as viewed from the upper left, and (2) is a perspective view as viewed from the upper right.

  The gas flow rate regulator 10 includes a cover 40, a gas pressure decompressor 11, a dial type flow rate regulator 20, an indicator 30, and a flare 50.

  The cover 40 is a housing that houses the gas pressure decompressor 11, the dial type flow controller 20, the indicator 30, and the flare 50.

  The gas pressure decompressor 11 includes a gas pressure decompressor body (hereinafter also simply referred to as a decompressor body) 12 and an inlet plug 13. The decompressor main body 12 decompresses the supplied oxygen gas. As described above, the inlet plug 13 is a connection member for mounting the decompressor main body 12 on the gas outlet 5 of the oxygen supply box 3. Oxygen gas is supplied from the gas outlet 5 to the decompressor main body 12 via the inlet plug 13, and the pressure is reduced from about 0.4 MPa to 0.3 MPa in the oxygen supply box 3, for example.

  A dial-type flow controller (hereinafter also simply referred to as a flow controller) 20 includes a dial-type flow controller body (hereinafter also simply referred to as a flow controller body) 21, a dial 22, a flow scale 23, and a hose port 24. Consists of. The flow controller main body 21 adjusts the flow rate of oxygen gas. One end of the flow controller main body 21 is directly connected to the decompressor main body 12 and oxygen gas is supplied therefrom, and the other end has a hose port 24. The dial 22 is provided on the upper part of the flow controller main body 21 and protrudes from the upper part of the cover 40. The flow rate scale 23 is provided in front of the dial 22 protruding from the cover 40 (see (1) and FIG. 3 in FIG. 2).

  The oxygen gas supplied to the flow rate regulator main body 21 is adjusted to an arbitrary flow rate by manually rotating the dial 22 and flows out from the hose port 24. The flow rate of oxygen gas is selected from any of the preset flow rates of 0, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 10, 15 L / min. can do. When the dial 22 protrudes from the upper surface of the gas flow rate regulator 10, the flow rate scale 23 can be selected while observing the flow rate scale 23 indicating the flow rate of oxygen gas without being covered with the hand. In addition, the set value of the flow rate is arbitrary and may be a flow rate other than these.

  The indicator 30 is an area-type floating gas flow rate indicator, and is located in front of the flow rate regulator 20 (on the opposite side to the gas pressure decompressor 11), and includes a gauge tube 31, a tube fitting 32, and a gauge fitting 33. And a cap 34. The gauge tube 31 is made of a transparent cylindrical resin taper tube, and has a spherical float (not shown) enclosed therein. A tube fitting 32 is connected to the lower end portion of the gauge tube 31 and connected to the gauge pipe joint 33 through a hole provided in the upper side surface, and the upper end portion is sealed by a cap 34.

  The oxygen gas whose flow rate is adjusted by the flow rate regulator 20 is supplied from the hose port 24 to the tube fitting 32 via the indicator connecting hose (not shown), and flows into the gauge tube 31 from the lower end of the gauge tube 31. The oxygen gas that has flowed into the gauge pipe 31 pushes up the enclosed float, and the float stops at a position where the force of pushing up and the weight of the float are balanced, and visually checks whether oxygen gas is flowing at the position where the float stops can do. Furthermore, the oxygen gas flows out from the gauge pipe joint 33 through a hole provided in the upper side surface of the gauge pipe 31.

  The gas flow rate indicator 30 is not limited to the area-type floating type, and any indicator that can visually confirm that the gas is flowing may be used. Further, since the gas flow rate set by the flow rate regulator 20 is flowing, it is only necessary that the indicator 30 can confirm that oxygen gas is flowing. Therefore, it is not necessary to measure the gas flow rate with the indicator 30, and when the gas flow rate of a certain amount or more is flowing, the float may come into contact with the upper end of the gauge tube 31 and stop. Therefore, the gas flow rate regulator 10 can be made compact.

  On the other hand, a portion of the front surface of the cover 40 where the gauge tube 31 is located has an opening 41 so that the gauge tube 31 accommodated in the cover 40 can be visually observed. If the opening 41 is opened so that the gauge tube 31 can be seen from the three directions of the front and both sides of the gas flow controller 10, the visibility of a float (not shown) floating in the gauge tube becomes good. ,preferable. In addition, since the gauge tube 31 is located at the lower part of the front surface of the cover 40, there is no inconvenience that the oxygen gas flow rate is covered by a hand and cannot be visually observed when the dial 22 is selected by operating the dial 22.

  The flare 50 is provided in the lower part of the gas flow controller 10, and one end of the flare 50 protrudes from the cover 40. The oxygen gas flowing out from the gauge fitting 33 is supplied to the flare 50 from an elbow 51 provided at the other end of the flare 50 located inside the cover 40 via a flare connecting hose (not shown). Is supplied to the humidifier 6 connected to the flare 40 protruding from the air.

  The oxygen gas supplied to the oxygen supply box 3 by the gas flow controller 10 is decompressed to a constant pressure, adjusted to a predetermined gas flow rate, and then a flare 50 provided on the lower surface of the gas flow controller 10. It is supplied to the humidifier 6 attached via (see FIGS. 2 and 3). The oxygen gas supplied to the humidifier 6 is humidified in the humidifier 6 and then supplied from the gas supply port 7 to an oxygen mask (not shown) via a gas supply hose (not shown) and is exhaled by the patient. The

  The gas flow rate regulator according to the present invention is suitable as a gas flow rate regulator for medical gas supply equipment with an integrated indicator, which is compact and does not interfere with medical practice, and is not damaged by contact. is there.
